Abstract: The stability of Cu( Ⅱ)-12-(2'-hydroxy-5- substituted benzyl) - 1,4,7, 10- tetraazacyclotridecane-11, 13-dione-a-aminoacids ternary systems has been studied by pHtitration method at 25.0±0.1℃and I= 0.1 mol/L KNO3.The formation constants of binary and ternary complexes were obtained.The structures of the complexes and effects of substituents were also discussed.

Key words: Stability of complexes, Functionalized macrocyclic dioxotetraamine, a-Aminoacids, Copper(Ⅱ)
